人比黄花瘦 comes from a 词 (ci2) written by 李清照 (li3 qing1 zhao4). "黄花"
is "菊花", chrysanthemum. "瘦" is thin. The poet compares herself with
the flower to illustrate her weary look (because she misses her
husband dearly).

In 《新结婚时代》, after the man refused to use the title "人比黄花", the editor (girl in pink with a ponytail) joked about changing it to "地下通道的无头女尸" (headless body found in the tunnel), which is more literal and "catchy."
